How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
A JSON object containing the ETH balance (as a number), USDC balance (as a number), the queried wallet address, and the network name ('base').
Example use cases
Agent wallet fund verification
“Before executing that transaction, check how much USDC and ETH is available in wallet 0xdD1729943bf7C408456cef52886ad12B05B57dC2 on Base so I know if there are enough funds.”
DeFi dashboard balance display
“Fetch the current ETH and USDC balances for address 0xAbCd1234567890AbCd1234567890AbCd12345678 on Base and show me the numbers.”
Automated low-balance alert
“Check the USDC balance at 0xdD1729943bf7C408456cef52886ad12B05B57dC2 on Base — I want to know if it has dropped below my threshold.”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-request lookup of ETH and USDC balances for a specific wallet address on the Base network without setting up your own blockchain RPC infrastructure. Ideal for agents that need lightweight, on-demand balance checks without managing API keys or subscriptions.
Side effects
- Invalid or malformed address returns an error or zero balances
- Address not found on Base returns zeros for both ETH and USDC
- Network unavailability or RPC issues may cause a failed fetch
- Payment failure (insufficient x402 USDC payment) results in 402 response and no data returned
